Service. Self-Study Programme 276 The Phaeton Automatic Proximity Control (APC) Design and Function If a driver attempts to activate the vehicles cruise control system (CCS) in the heavy traffic scenario shown below to cruise along in a relaxed manner, he will soon have to brake because of the frequently changing distances to vehicles ahead. The APC system has learned its lesson from bats. In much the same way as bats use ultrasonic waves to find their way about their surroundings, the Automatic Distance Control (APC) scans the traffic situation ahead of the vehicle by means of millimetre wave radar and controls the distance to the vehicle ahead on the basis of this data. The CCS can be expanded to include a proximity-maintaining function which allows comfortable and stress-free driving even in heavy traffic.
